1 Claim.

This invention is directed to a metal cement involving the use of certain ingredients tending to a more effective, lasting and powerful cement for use in connection with metals.

5 The cement is made up of certain ingredients which may be identified as lacquer, iron filings, whiting, hydraulic cement and aluminum powder, and these ingredients are preferably, though not t necessarily, used in the following proportions: To 1% pounds of lacquer is added 5 pounds of iron filings, 1 pounds of whiting, pound of cement, and pound of aluminum powder.

While the various materials employed undoubtedly have other meritorious and advan- 15 tageous functions in the cement as a whole, it may be mentioned that as known to me as a result of tests, t1 e lacquer serves as a binder and mixing vehicle he iron filings serve to impart a metal finish to the cement, the whiting serves as a filler to close grain the filings, the cement is used as the hardening element, and the aluminum powder to -provide a smooth finish for the cement and prevent the compound from rustingwhen exposed to the weather. 25 It is, of course, to be understood that while the cement is made up of the ingredients mentioned and in the proportions above set forth as probably ingredients are put together and mixed well be- 10 fore the lacquer is added. The lacquer is then. added and mixed thoroughly and the mixture is packed immediately in air-tight containers. All ingredients must be measured accurately and extreme care must be exercised to prevent all dry 5 ingredients from being exposed to dampness.

I claim:-

A metal cement made up of the following ma-' terials in the proportions named:
